Background
• Active physicians prescribe activity• Medical students lifestyle predispose to low PA• No Romanian papers regarding PA on medical
students
Background• IPAQ- International Physical Activity Questionnaires • Set of instruments that can be used internationally to obtain
comparable estimates of physical activity.• Validated (400+ papers)• Easy to administer• Free to use
Physical activity – MET(Metabolic Equivalent of Task):• Sleeping 0.9• writing, desk work, typing 1.8• walking 3.0 mph (4.8 km/h) 3.3• jogging, general 7.0• rope jumping 10.0 https://sites.google.com/site/theipaq/
Objectives
Evaluate medical students’ physical status
Search for an association between MET score computed using IPAQ and BMI (Body Mass Index)
Seeking a correlation between MET score and heart rate/blood pressure recovery time after submaximal stress test
Material and Method
Cross-sectional study includes a convenience sample of 85 voluntary students (spring 2014).
“Short last 7 days telephone format” IPAQ
was administered.
Material and Method
Demographical data was recorded and the subjects underwent a cardiovascular stress
test (Schellong II).
Blood pressure and heart rate were
determined until reaching pre-test values
using a Sanitas SBC25 monitor.
Statistical analysis was performed using
Microsoft Excel and GraphPad InStat 3.06.

Results
Females present a higher PA score than males. Nevertheless,the difference was not statistically significant.n (p=0.1679).

BMI
• While BMI ranged from 17.17 to 28.08 comparing it across MET quartiles, we found the highest median on the first quartile (22.53) but with no statistically significant differences among the other quartiles (p=0.057).
• An association was found between MET lower than 1000 and BMI over 25 (p<0.05)
Results
Weak negative correlation (r=-0.18), statistically non-significant (p=0.09) between MET values and recovery time.

Discussions
• As compared with other studies our students seem to be more fit, with an normal BMI and a high level physical activities• The males from our sample scored lower PA level than
the females, probably due to our sample characteristics.• There are certain limits to our study - the sample is small
and due the physical component students with good physical status were more likely to attend.
Conclusions• Medical students in early years present a good physical
activity state, with an active life and appropriate nutrition. • As expected higher BMI was found in patients with lower MET-
minutes/week, overweight subjects presenting an association with MET-minutes under 1000.
• BP and HR recovery correlation with physical activity evaluated by MET need more data to gain a better perspective.
• Regular exercise is an essential part of a healthy lifestyle and medical professionals should maintain a good physical activity level in order to remain healthy and look credible in the eyes of their patients.
